Is this vulnerability remotely exploitable?

Yes, if an attacker can obtain or guess the `readOnlyMasterKey` and reach the Parse Server API, they can remotely call `POST /loginAs` to impersonate users.

What level of access does an attacker need to exploit this?

The attacker needs access to the `readOnlyMasterKey`. This could stem from misconfigured clients embedding the key, exposed configuration, logs, insider threats, or other security weaknesses that reveal the key.

What is the safest general fix pattern?

Correct the authorization logic so that the `readOnlyMasterKey` cannot perform any state-changing actions, including user impersonation, and enforce explicit privilege separation for sensitive administrative endpoints such as `/loginAs`.
